A neuron with two inputs computes

$z = w_1x_1 + w_2x_2 + b$

A teammate changed exactly one of its three parameters ( $w_1$ , $w_2$ or $b$ ) and did not write down which one, or by how much. Nothing else about the neuron changed. You have its outputs on three inputs from before and after the change:

input	$x_1$	$x_2$	$z$ before	$z$ after
$P$	$1$	$2$	$3$	$5$
$Q$	$3$	$2$	$7$	$9$
$R$	$2$	$0$	$7$	$7$

Before the change, the neuron output $z = 8$ for a fourth input, $S$ , with $x_1 = 4$ and $x_2 = 3$ .

What does the neuron output for $S$ after the change?
